在使用sqlplus执行sql脚本时，经常碰到向脚本传递参数的情形。类似于shell脚本的参数传递，我们同样可以向sql脚本传递参数，其方法是脚本后面直接跟多个连续的参数并以空格分开。本文描述该内容并给出示例。
1、SQLPlus 的帮助信息
下面的帮助信息是关于sqlplus调用带参脚本的说明
sqlplus -H
is: @|[.] [ ...]
Runs the specified SQL*Plus script from a web server (URL) or the
local file system (filename.ext) with specified parameters that
will be assigned to substitution variables in the script.
2、shell 提示符下sqlplus调用带参脚本
SQL> select * from v$version where rownum insert into emp(empno,ename,job) select 8888,'Bob Cheng','DBA' from dual;
SQL> commit;
[oracle@linux1 ~]$ more test.sql
set linesize 160
select empno,ename,job from &1 where upper(ename)=upper('&2');
exit;
[oracle@linux1 ~]$ sqlplus scott/tiger@rac11g @test.sql emp scott
old 1: select empno,ename,job from &1 where upper(ename)=upper('&2')
new 1: select empno,ename,job from emp where upper(ename)=upper('scott')
EMPNO ENAME JOB
---------- ---------- ---------
7788 SCOTT ANALYST
--注意，对于含有空格的调用需要使用单引号或双引号，如下示例
[oracle@linux1 ~]$ sqlplus scott/tiger @test.sql emp 'bob cheng'
old 1: select empno,ename,job from &1 where upper(ename)=upper('&2')
new 1: select empno,ename,job from emp where upper(ename)=upper('bob cheng')
EMPNO ENAME JOB
---------- ---------- ---------
8888 Bob Cheng DBA
[oracle@linux1 ~]$ sqlplus scott/tiger @test.sql emp "bob cheng"
